Instrument Description:

The Hensen Net was invented by Christian Andreas Victor Hensen (February 10, 1835 - April 5, 1924) who was a German researcher considered by many to be the 'father' of Biological Oceanography. Hensen is credited with first using the term 'plankton', and the Hensen Net is one of several sampling devices he invented to help with sample collection. The Hensen Net has a 'reducing cone' forward of the net mouth, a simple closure system and a cod end collection device.
